GLASS-MELTING POT.

Application led March 27, 1922. Serial No. 547,11.

T 0 (IN u-mm it may concern Be it known that l, CLINToN A. BOWEN, acitizen of the United States, residing at Corning, in the county ofSteuben and State of New York, have invented new and useful lmprovementsin Glass-Melting Pots, of which the following is ay specification.

This invention relates to melting pots, of the class known as continuousmelting pots, or devices of this character wherein the compound forproducing the glass is fed thereto; at one point and removedcontinuously thereirom at another point.

The prime object is to improve the construction and increase theetiiciency, utility, and economy of construction and operation otdevices of this character.

With these and other objects in View,

which will appear as the nature of the invention is better understood,the same consist-s in an improved construction and novel arrangement ofthe parts as specifically hereinafter set forth and claimed. In thedrawings formingl part. of this specification wherein is illustrated thepreferred form of the embodiment of the invention capable ot carryingthe same into practical operation z- Figure 1, is a verticallongitudinal section, and

Fig. 2. is a horizontal sect-ion on the line 2 2 of Fig. 1.

The improved device is constructed in one single mass of the refractorymaterial usually employed in manufactur1n,f r meltingl pots for ,glassand for similar purposes, and comprises a body portion represented as awhole at 5` with a bottom 6, vertical walls 7, and dome like top 8. Theimproved body is designed to be located within the furnace in the usualmanner.

rlhe `Front of the body 5 is provided with a well or chamber 9 which isin communication with the interior of the bodvbv means of a passage 10,between said well and body. said well being formed by a. vertical web 11constructed integrally with the vertical wall ot the body 5 to the rearof the front end thereof, and said passsage 10 beineY formed byterminating the web 11 a distance from the bottom 6. A

Intermediate the front vertical Wall, the body 5, is constructed with anenlarged pon tion 12, having au inclinedopening 13 which communicateswith the Well 9. The Opern ing 13 is designe-cl to allow molten glass tocontinuously flow by gravity from the well 9 and therefore its heighthfrom the bottom 6 ofthe body is approximately that of the normal levelof glass.

t will be seen that the refined molten glass will flow from the body 5through the passage 10 into the well 9, and so supply the latter. Fromthe well 9 the glass will flow by gravity down the inclined ope-ning 13into a trough, or other suitable conveyor (not shown).

The device is particularly designed to be used in connection with acontinuous tubedrawing apparatus, and in actual practice the glass isled by meansof a trough onto the rotating spindle of such. apparatus.

The end of the body 5 opposite to the well 9. is constructed with anopen mouth 14, which is in direct communication with the interior of thebody. The mouth 14 is located above the normal level of the glam andnear the dome of the body, and by prete-rence. it is formed ofsuiiicient size to permit theinsertion of a ladle, or other apparatus',into the body, for the purpose of charging or discharging' the contentsofthe body. In the mouth 14, there is formed a seat 15, for a removablecover or door 16.

As the `dass in the body is being continuously discharged therefromthrough the iuclined opening 13, it is necessary that the supply in thebody be replenished at very frequent intervals. ln actual practice thedevice forming the subject matter of this invention is used in a`reheating furnace, and, therefore, molten glass is ladled from anotherfurnace and deposited in the body 5. l'n the ordinary form of devices ofthis character, considerable heat is lost from the interior of the body5, each time the door 16 is removed to permit the insertion of a ladleof molten glass.

To overcome this difiiculty, and thereby prevent excessive loss of heat,an 'inclined opening 17 is formed in the bottom of the mouth 14 belowthe door opening 15. The opening 17 is oi` sutiicient size to permitmolten glass deposited on the bottom of the mouth to quickly flow int-othe body 5.

It will be observed that by my improvement t-he mouth 14 of the pot canbe sealed by the door 16, and the body 5 charged with SitiA m Mmmm lovolof the glass bhoreim 2. A glass; moting poi: compose@ ie.
